configuring emacs as a programmer's editor

OK, I have used emacs as just a clone of Notepad for quite a while.  I
know that is under-using it, but I found configuring it to be more
useful to me a bit onerous.  I find the emacs documentation a bit dense
on one side, and short of the details and examples I need on the other.

I have a basic .emacs file, appended below, that seems like it should
support most of the programming languages I use.  I constructed it by
copying and pasting portions of .emacs files I found published on the

I need something that will work for me on both Windows XP and SUSE
Linux 10.  But on Windows, I have MS Visual Studio, and so need emacs
to support primarily SQL, Perl, PHP, while on Linux, I need it to
support these plus the C++ and fortran gcc compilers.  While I do a lot
of Java, I use Netbeans almost exclusively for my java programming.
Finally, I need to be able to specify whether to submit my SQL to
PostgreSQL or to MySQL, if that is possible.

I suppose I have two questions.  1) How do I modify the .emacs file
I've managed to cobble together to fully support my needs?  and 2)
Although I can get into perl mode (using cperl-mode, I think), by
loading or creating a perl script file, I find invariably that the run,
kill, next error, and check syntax items on the Perl submenu are
disabled.  Why?  And how do I fix that?  I have guessed that emacs is
largely written in, and configured using lisp, and that to really
understand this, I should learn lisp, but the time I have for that in a
significant way is not yet available, so lisp code, for this
fortran/C++,Java/SQL coder, is about as intelligible as Greek (which I
don't understand, being a unilingual anglophone).  There is only so
much time in a day and I can't get to everything I want to do.  :-(
I'd make better progress if I could find a resource that relates lisp
syntax and style to their counterparts in the languages I know, but
that is another issue.

For the present, I'll be content if someone could help me get emacs
configured on Windows and Linux to meet my proximate needs.
